E-Ink displays for hobbyists are either too small , too expensive
or don't have any documentation at all. The cheapest way seems
to use rooted Kindles , and at that point you don't need a Pi at
all.

If you aren't using an E-Ink display , cheap Android tablets
just work and are available now. Furthermore the touchscreens
of those devices tend to work by default , which is not what
can be said of the Pi (except with official touchscreen).
